Current collectors incorporating electrohydrodynamically deposited carbonaceous material

Abstract:

Exemplary energy storage devices, battery cells, and batteries of the present technology may include a cathode active material disposed on a cathode current collector. The devices may also include an anode active material disposed on an anode current collector. At least one current collector of the cathode current collector or the anode current collector may include a continuous layer of a carbon-containing material positioned between the current collector and the active material.
